ADS device

The TwinCAT ADS Device: SMS COM Server is a software driver that can send SMS messages over a GSM modem.

Because the SMS server is a pure software driver, it can be described as a virtual field device (automation device). For this reason it makes a Beckhoff ADS (Automation Device Specification) interface available to other communication partners (e.g. the PLC or Visual Basic programs). The use of the ADS standardises access to the TwinCAT SMS device, placing it in the group of available virtual field devices.

Properties:

Implementation as an NT COM Service.
A PLC program is not necessary.
Implementation as a Beckhoff ADS device, with ADS port number 10400.
Is started and stopped along with TwinCAT.
The GSM modem must be connected via a serial data cable to the serial interface of the TwinCAT PC.
The TwinCAT SMS Server Configurator sets the communication parameters for the connected GSM modem.
Sending SMS messages of up to 160 characters.
